Linear, group and single landings in landscape design.
The most common — shrubby. These are frequently used landings in landscape design.
Linear landings are used to decorate squares, boulevards, alleys and playgrounds. Planting of plants is carried out in one or two rows in a checkerboard pattern from one of any breed. Both rows consist of homogeneous species of trees or shrubs.
With a small width of the alley, overgrown trees can form a closed vault of greenery above the path, creating a tunnel. Shady alleys are among the best decoration of a park or garden, as well as a boulevard on the street or along the waterfront. They can lead to the building, the central square of the park.
In the latter case, an interesting variant of radial alleys, of which one of them is in the shade at any time of the day. In natural-style gardens and parks, alleys can meander capriciously. Thus, the so-called belt alleys encircle a garden or a park. Alleys should not be designed in the direction of the prevailing winds, which opens up wind and dust access to green spaces.
Group plantings of ornamental plants are made up of some trees or shrubs, or of both. Depending on the size of the material in groups, trees are placed at a distance of 1–1.5 to 3–4 meters or more, and shrubs 0.7 to 1–3 m. Larger shrubs are planted at a distance of 1-3m, medium — 0.8–1.5m, small — 0.7m.
Trees and shrubs in groups are placed freely, without observing a chess, ordinary or other order. At the same time, they move from tall plants to lower ones, fringing the trees with shrubs in one or several tiers, and the latter with perennials. Groups are homogeneous or consisting of several species, taking into account their biological and decorative features.
Group planting of shrubs is carried out on the edges of tree species, to create undergrowth, on lawns and lawns, at intersections and bends of roads, for decoration boundaries, corners, central places of the site. Shrub groups are created taking into account the terrain and the environment, growth strength, requirements for soil, light, moisture and other biological characteristics of plants.
It is not recommended to mix conifers and hardwoods. Groups are made up of one breed – homogeneous or several – heterogeneous. Groups can be dark or light, compact or transparent, one-color or multi-color. Shrubs with continuous flowering from early spring to late autumn are selected in groups. With simultaneous flowering, the harmony of colors of flowers is observed. Created from 3, 5, 7 or more shrubs.
With three shrubs, planting is carried out in terms of a versatile triangle. With four – the fourth is planted in the middle, but not in a row with other shrubs. The fifth is not exactly in the middle of it. There should be no symmetry.
Places for planting shrubs are pre-planned by driving stakes. Good groups of a large number of flowering shrubs, with a variegated crown, coastal, weeping shrubs, Japanese shrubs. With a large number of shrubs, planting is carried out in two to three adjacent groups. Groups should be lively, not boring, but not restless. Rounded and elliptical shapes should be avoided – they are boring. Groups with large protrusions or notches. The larger the group, the more genera and species of shrubs can take part in it, and the richer the group will be. In this case, one of any breed should dominate, giving a certain tone to other breeds that are part of the group. It is recommended to diversify the masking of road intersections by forming groups of park roses, tree-like peonies, flowering shrubs, standard plants or deciduous-decorative ones.
Shrub plantings depend on the conditions of the area, soil, future limiting sizes of shrubs, light requirements. They are also planted with or without subsequent thinning. Group landing sites are dug up annually. The soil is always kept loose and free from weeds. Groups of plants growing abroad are pruned without violating their natural beauty.
They are decorative ordinaries planted among lawns, fields, lawns, at corners, at corners of paths, on the ledges, at the entrances. Shrubs with spectacular forms are suitable for single plantings – standard, weeping, drooping, with pyramidal and columnar growth, with spreading branches, beautiful ornamental leaves, flowering. Tapeworms, especially standard ones, should be planted with support. In closed groups there may be common supports in the form of stakes, with crossbars disguised with greenery. In a small number, single plantings of shrubs give a decorative effect, with a large number of them, this effect may disappear.
